A mobile gaming advertiser wants to optimize their ads to target those who are likely to spend more. Which bidding optimization should they use?

Value-Based Optimization (VBO) is the correct choice because it specifically optimizes for the value of conversions, aiming to acquire users who are likely to spend more or generate higher revenue. For a mobile gaming advertiser, this means the system will prioritize showing ads to users predicted to make in-app purchases or have a higher lifetime value. App Event Optimization (AEO) optimizes for specific in-app events, but not necessarily the value of those events. Cost Cap Optimization focuses on maintaining a specific average cost per result, which doesn't directly address maximizing user spend. Maximum Delivery Optimization aims to get the most results for the budget, without considering the quality or value of those results.
